COVID Alert is Canada's free exposure notification app.


    Available for iOS and Android



Together, let's limit the spread of COVID-19 and prevent future outbreaks.

  • COVID Alert helps us break the cycle of infection. The app can let people know of possible exposures before any symptoms appear. That way, we can take care of ourselves and protect our communities.


Why download COVID Alert app

Along with physical distancing, wearing a mask and other important steps, knowing what to do if you have been exposed to COVID-19 (coronavirus) is another key way to protect yourself and your community.

But how do you know if you’ve been exposed to COVID-19? And, if you get sick, how can you make sure even strangers you’ve been near take the right steps to protect themselves and others? That’s where COVID Alert comes in.

With the free COVID Alert app, you can:

  • get a notification if you may have been exposed to COVID-19
  • get advice on what to do next
  • tell nearby app users if you test positive for COVID-19, without sharing any personal information

COVID Alert will not:

  • collect, store or access any personal data, or health information
  • tell you if you’re currently near someone who’s tested positive
  • tell you about outbreaks in your city or neighbourhood

COVID Alert is completely voluntary. You choose to download, use or delete it. The more people who use it, the more effective it will be in helping to protect each other and our communities.
